   Good point, @MaxGekk . Could you give us your use cases, @ulysses-you ?
   
   IMO, in the Spark SQL world (Spark Thrift Server or Spark SQL Shell), the following is the only way.
   ```
   spark-sql> set spark.sql.session.timeZone;
   spark.sql.session.timeZone	America/Los_Angeles
   Time taken: 0.034 seconds, Fetched 1 row(s)
   ```
   In other words, we cannot use it in Spark SQL DML statements. I guess you have some use cases for that.

   @dongjoon-hyun @MaxGekk The difference between config and function, I think the later can calculate with other data. That says we can do some compare or save the data into storage engine. We introduce many date-related function in recent version, then the timezone is important.
    
   > In other words, we cannot use it in Spark SQL DML statements. I guess you have some use cases for that.
   
   ah, actually I have not seen some case with it and just consider we may need it sometime.

Review comment:
       We don't need to print `an offset from UTC (e.g., +08:35)`? It seems presto/sql server do so (IMO printing it looks meaningful).

   @dongjoon-hyun @MaxGekk The difference between config and function, I think the later can calculate with other data. That says we can do some compare or save the data into storage engine. We introduce many date-related function in recent version, then the timezone is important.
    
   > In other words, we cannot use it in Spark SQL DML statements. I guess you have some use cases for that.
   
   ah, actually I have not seen some case with it and just consider we may need it sometime.
   
   We can also show the offset as @maropu said that make it different with `set spark.sql.session.timeZone`.

   Good point, @MaxGekk . Could you give us your use cases, @ulysses-you ?
   
   IMO, in the Spark SQL world (Spark Thrift Server or Spark SQL Shell), the following is the only way.
   ```
   spark-sql> set spark.sql.session.timeZone;
   spark.sql.session.timeZone	America/Los_Angeles
   Time taken: 0.034 seconds, Fetched 1 row(s)
   ```
   In other worlds, we cannot use it in Spark SQL DML statements. I guess you have some use cases for that.

   @dongjoon-hyun @MaxGekk The difference between config and function, I think the later can calculate with other data. That says we can do some compare or save the data into storage engine.
   
   > In other words, we cannot use it in Spark SQL DML statements. I guess you have some use cases for that.
   
   ah, actually I have not seen some case with it and just consider we may need it sometime.
